Calibrate and diagnose control valves and their positioners. Covers stroke calibration, bench set, valve signature, and diagnosing stiction and hysteresis in service.
Control Valve Calibration & Diagnostics starts at the field device, not the graphic. Confirm supply, loop resistance, and whether the transmitter is talking analog only or HART. If the valve will not stroke, prove air, prove the command, then prove the mechanicals. Signature and stiction come after the obvious, not instead of it.
If the valve will not stroke, prove instrument air at the positioner, prove the 4-20 mA command at the terminals, then prove the stem actually moved. Bench set and signature come after that. Stiction and hysteresis show up in service, not on a workbench with the actuator off the body.

This page is the crawlable outline Google and a curl-no-JS client can read. Quizzes, video, and progress tracking live in the course player.
I&E technicians who own loops, valves, and transmitters, and who have to defend a calibration in the control room.
Who it is not for: license mills, VR demos, or anyone looking for a fake testimonial. We do not invent customer quotes. Certificates of completion after quizzes go in the file. They are not a journeyman card, an ISA credential, or NFPA 70E qualification by themselves.
ForgeLine Academy currently lists 78 industrial maintenance courses. 44 of those are free (Mechanical and Electrical). Premium unlocks I&E (18) and Engineering (16). That is the whole catalog — not a 22-course teaser and not a four-hour overview of the plant. Call +1 580 421 5714 or email support@forgelineacademy.com for plant cohorts and on-site classes.
Control Valve Calibration & Diagnostics is one course in that 78-course ladder. Mechanical and Electrical remain free. I&E and Engineering are premium. On-site and plant cohorts are scheduled through on-site training or plant support.
Training is educational. It does not replace your site's lockout/tagout, permits, PPE, or required licenses. Certificates of completion go in the file. They are not a license.
